AK-ER65SD
Standard:
EN ISO ——
AWS A5.28 ER90S-G
GB/T 8110 ER65-G
Characteristics and Applications: AK-ER65SD is NiMo type high toughness low alloy steel gas shielded welding wire, all position welding process performance is excellent, arc stability, small spatter, beautiful weld shape, deposited metal has good mechanical properties. Suitable for 650MPa steel structure welding, commonly used in hydropower, construction machinery, lifting machinery, ships, bridges, pipelines and pressure vessels and other structures of the welding.
Note:
1. The protective gas is rich argon gas with a flow rate of 15-20L/min.
2. The impurities such as water, oil and embroidery must be removed from the welding area.
3. When the current is more than 250A, the wire dry elongation should be 20-25mm.
